Service lewmar constellation drive type 2

[kalusta]

Hi,
Our Autopilot startet recently to make some unusual Noise and is going hard on some points when the rudder is under pressure. Manual steering is Ok however.
It seems the problem is coming from the Lewmar Constellation drive unit.
I have a 89300086 Constellation Drive Kit, 1/4HP 12V 5/8"P from 2018 installed and since then sailed about 12.000 nm.
I am looking for technical drawings how to service the unit and where to get replacement parts such as gearings etc.
Has anybody experience with this ?

Thanks,
